The challenges of designing a placebo static magnet for double blind clinical trials.

Clinical trials involving static magnets pose a difficult dilemma for researchers; how to “protect the blind”. That is, seeing you can’t hide a magnetic field, how do you prevent a patient from testing the magnet with, say a paper clip?

 

For studies like Vallbona it’s not such an issue, as subjects only wear the devices for 45 minutes and researchers can closely monitor subjects to make sure no one “cheats”. However, many times you want to see the effects over days or even weeks and you can’t keep them under surveillance 24/7. Segal tried to counter this with a weak magnetic placebo, but the strength of the field entering the body was significant at 72 mT. So there is an argument that this was actually a dose-comparative study and not comparing with a true placebo. In addition, a research paper by Greaves & Harlow noted that…

Quadrapolar magnet generating field gradient effects on kainic acid induced neuronal swelling

 

There are a number of effects produced by inhomogeneous static magnetic fields like that of Q magnets, the main ones being increasing the pain threshold and dampening sensitized nerves. The following study looked at the effects on cell membrane stabilization.

These effects at a cellular level could help explain the observations of Q magnet therapy on haematomas.

OBJECTIVE: Swelling is a final common pathway to neuronal death following diverse insults that damage the central nervous system. Here we have tested the effect of a static magnetic field on neuronal edema induced by the excitotoxin, kainic acid (KA), in an effort to identify a new treatment strategy.

Effects of Moderate Static Magnetic Fields on Nerve Conduction and its Relevance to Q Magnet Therapy

Pages on the Q magnets  website such as “how Q magnets work” and “magnetic field gradients” describe how inhomogeneous static magnetic fields (iSMF) affect nerve fibres. A recently published study provides further confirmation of the physiologic effects as we have described.

Okano et al. (2012) The Effects of Moderate-Intensity Gradient Static Magnetic Fields on Nerve Conduction. Bioelectromagnetics. 2012 Mar 16.
PMID, doi

SUMMARY:
The effects of SMF on nerve conduction are unclear and the underlying mechanisms not well understood. This study focused on the effects of a moderate (iSMF) on membrane excitation and refractory processes on frog sciatic nerve fibres.

Positioning Neuromagnetics in the “window of effectiveness” for magnetic therapy.

Recent studies investigating the therapeutic effects of static magnetic fields propose there likely exists a “physiologic window” of effective magnetic field properties. This is certainly our experience and more research needs to be conducted to understand the parameters of this window for optimal therapeutic effect.

The fact is, there are 7 variables when it comes to the application of static magnet devices. If the offending target tissue (e.g. sensitized C-fibre nerves in spine) is enveloped by an optimized field by correctly applying the most appropriate device, then remarkable outcomes for pain sufferers are sometimes possible. Just like in the case of John with a 27 year history of back pain.

After thousands of patients treated and numerous clinical trials and animal studies, there is now enough evidence to recommend protocols for effective Q magnet placement.

Inhomogeneous static magnetic field (magnetic therapy) effects on TMJ Pain

DISCLAIMER:
The type of magnet used is this study is not a Q magnet.
The safety and effectiveness of Q magnets has not been established in the treatment of dental or TMJ pain.

 

A recent paper studying the effects of an inhomogeneous magnetic field on dental pain was published in the International Journal of Radiation Biology. While the size of the study was relatively small (29 for TMJ pain) and of short duration (5 min), none the less, it demonstrated a significant pain relieving effect over placebo. The magnetic device used in this study was not a Q magnet, but being a multipolar magnet they share many of the same characteristics.
